. GGlaims. roman-14 1) A This invention relates to radiators.

An object of the invention is the provision of a radiator which may be used for coolin or heating. purposes in which a plurality of spaced fins surround pipescarrying the heating or refrigerating medium, the fins being in the form of spaced plates providing air chambers with the alternate ends of the chambers being closed while the remaining. ends are open for the purpose of providing circulation of air through the plates. f 1

Another objectof the invention is the provision of a radiator formed of a plurality of thin metal sheets having Ush'aped clips for connecting the side edges of the plates together, the U- shaped clips being staggered upon opposite sides of the radiator so that air channels formed between the plates willhave one .end open and the other end closed.

'80 A further object of the-invention is the pro vision of a radiator having a plurality of radiate ing fins formed of sheets of metal spaced apart along pipes; which carry the. refrigerating 'or heating medium, thesheets being provided with spaced punched lugs which are adapted to be snapped into place through openings in Ll-shaped members that connect the. opposite edges of the plates together, the U-shaped members being staggered upon opposite edges of the plates so that the air channels'fo'rmed between the plates will have one side edge open and the other closed to provide for a tortuous path for the air which comes in contact with the plates.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawing forming a part of the specification; nevertheless, it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications which shall define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 1 is a side elevation of a radiator constructed in accordance with the principles of my invention,

Figure 2 is a transverse vertical section taken along the line 2-2 of Figure 1,

Figure 3 is a horizontal section taken along the line 33 of Figure 2, and

Figure 4 is a horizontal section taken along the line 4-4 of Figure 2.

Referring more particularly to the drawing, 55 and 11 designate a pair of headers which con tain a refrigerant or a heating medium and these headers are connected in the usual manner, one with an inlet pipe and the other with an outlet pipe. These pipes are connected either with a heater or arefrigerating apparatus in any well known manner. if r Tubular members 12 and 13 are connected to the headers, 10 and 11 .and are in open communication with the same. Any number of these "tubular members may be employed forthe purpose.. These tubular. members provide means for transmission of fluid from one header .to the other. The tubular members areiremovably secured to the headers by means of nuts 14'of well known construction.

The radiating section of the device consists of a pluralityof spaced plates 15 and these plates are vertically disposed and located in parallel relation to providea plurality of air channels 16 and 17. The platesfare provided with openings 18 and 19 to snugly receive the tubular members 12 and 13, respectively. The metal around these openingsis not entirely cut away but is formed into a plurality of lips 20 which snugly engage the outer walls of the tubular members 12 and 13 and these lip s'provide inner spacing members for said plates, It will be noted that the lips 20 are located at right angles to the planes of said plates. One side of each face is provided with a plurality of punched-out lugs 25 While the op- 35 posite side is provided with punched-out lugs 26. These lugs are stamped out from the body of the plate to provide elliptical openings starting from the maximum point of the elliptical curve and continuing with a parabolic curve to the horg izontal surface of the fin plates. Any number of the lugs or burrs may be stamped along the edges of the plate as may be necessary for the purpose.

A U-shaped member, generally designated by the numeral 27 has a bridging portion 28 located between a pair of the plates 15 along the vertical edges of the plates and a pair of returned flanges 29 located in spaced relation with the side flanges 30 of the U-shaped members. Each of the flanges is provided with openings 31 into which are adapted to be snapped the lugs or burrs 26 of one plate and the lugs 32 upon the opposite face of the next adjacent plate. By this means the U-shaped members 27 rigidly se- '0 cure the side edges of the plates 15 together.

It will be noted, however, that where the bridging portion of the U-shaped member 27 is received between a pair of plates 15 it will subs flntially close the air space 16 at that end. The 1 16 and 1'? are in staggered relation upon opposite It will be seen by this" construction that the air can enter the chain"- sides of the radiator.

nels 16 and 17 upon opposite sidesof the radiator but through alternately disposed openings upon opposite sides thereof. e

It will be seen by this construction that a large area of radiating surface is provided and a large air capacity is also provided in the air channels 16 and 1'7 to provide for a large quantity of air passing through the radiator.
